I know a guy in his late 20s with this name, even before Leighton Meester hit the scene I always thought his name was feminine due to it starting with Leigh-. though he pronounces it Lay-ton. (I dislike him strongly as a person so I never got around to actually judging this name as it will always be associated with him for me)

Well Rowan I was thinking was a girls name as I have only remembered ever heard it as a girls name recently, then I read lizben's comment about Mr. Bean aka Rowan Atkinson and yes it is definitely a male name. I'm not really into this boys name on girls trend but alot of these names I hadn't heard of/remembered hearing of so I automatically associate them with the ladies.
